Risible describes something that is laughable or amusing, like seeing a very large man trying to get into a very tiny car.

Risible is a fun word to say (it rhymes with visible), but it's just not used all that much, maybe because it's a little formal. But if you started saying the word risible all the time, that itself might be kind of risible. Fun — and less stuffy — synonyms include amusing, comic, comical, funny, laughable, and mirthful.
